I'm not sure since when but it states so clearly on the main page: "We
seem to have a problem with wiki-spam from various sources. I am going
to make the wiki read only while I resolve the problem & probably create
a username/password system to help protect us from this evil scourge!"
I didn't find any mention of where you can apply for a
username/password..

Dalibor,
Is there any specific reason that you want TT support? TT support is
obsolete / deprecated as 2.6 kernels have SKAS0 support which is a lot
better. Even if you did get it to build, it's likely to cause problems
(such as the UML kernel not booting up, etc.). I was able to get it to
work on 2.6.17-9, but I think only after I disabled SMP support. For
more details, check out my thread:

I realize that today. I used TT mode so i can use PT_PROXY to debug
networking stack in kernel but it was way ago.

I don't know why Jeff didn't put nothing in Kconfig like TT is obsolete
try using SKAS0 mode you can also debug in SKAS0. And site is also
obsolete. Every information is for 2.4 tree. Need update.
I tried today debuging in SKAS0 mode and it's working great. I don't
have problems stopping on breakpoint everything seems ok.

I was using 2.6.14 in TT mode and for debuging purposes but I had
problems with gdb. When I put breakpoint on some function and I trigger
that break I can't step (source debugging) the subroutine code because
gdb is stepping the code from alarm_handler function defined in
os/signal.c. I tried disabling CONFIG_UML_REAL_TIME_CLOCK and
(gdb) handle SIGALRM pass nostop noprint
(gdb) handle SIGVTALRM pass nostop noprint
and still the same. But on 2.6.17.10 in SKAS0 mode everything work
great.
thnx in advance

Sounds interesting. I think it would be interesting to know in greater
detail what and how you're using it (and how others are using it as
well). I think that the UML community would benefit alot if more and
more people share how they're using it and how's it's benefiting them
including detailed examples.

I mentioned this in my previous thread and Jeff redirected me to:
http://uml.harlowhill.com/ Unfortunately, it's read only. The problem
is that for anyone to share their experience, notes, tips, etc, they
would have to post it on their own site (if they have one). Even then,
it would mean that you have to search and try to find these web sites.
It would be great to consolidate this information into a single
knowledge base. I can understand that Jeff's too busy working on UML to
bring us more features and better performance :) to have time to
maintain the wiki more regularly and to allow edits, etc.
Unfortunately, I have almost no wiki experience so I can't really help
:(
